If (\sin x=0), what is the value of (\cos x) at (x=0)?
Answer and explanation
Correct answer: \(1\)
At \(x=0\), \(\cos 0=1\). Therefore, the correct option is \(1\). Note that \(\sin x=0\) can also occur at \(x=n\pi\), but the question specifically asks for \(x=0\). Exam tip: Remember that \(\sin 0=0\) and \(\cos 0=1\).
